Google Antigravity — Free AI IDE Preview

Google Antigravity is one of the most interesting new developer tools of 2026. Launched in November 2025 as a free public preview, it is Google's answer to Cursor — an IDE built around agentic AI from the ground up, not AI bolted onto an existing editor. With Gemini 3.1 Pro baked in and free access during preview, it is worth exploring if you build software.

What You'll Learn

• What Antigravity is and how it differs from traditional IDEs
• How to get access (antigravity.google)
• Key features available in the public preview
• How it compares to Cursor and VS Code
• Special benefits for Jio Pro users

What Is Google Antigravity?

Antigravity is Google's agent-first integrated development environment. "Agent-first" means the AI is not a sidebar feature or a plugin — it is the primary interface. The core workflow is:

1. Describe a task or feature in natural language
2. The agent (powered by Gemini 3.1 Pro) reads your codebase, plans the implementation, and executes it
3. You review, approve, and iterate

The name references the idea of removing friction from software development — like defying the gravity that slows down coding. During the public preview, it is free with full Gemini 3.1 Pro capabilities.

🇮🇳 India Note: Google launched Antigravity with a specific focus on Indian developers. The early preview was made available in India at the same time as the US, and Jio Pro users (with Gemini AI Pro active) get access to the premium Gemini 3.1 Pro Ultra model — the more capable variant — at no additional cost.

How to Get Access

1. Visit antigravity.google
2. Sign in with your Google account
3. Click Join Preview
4. Fill in the brief questionnaire (current role, primary language, intended use case)
5. Access is typically granted within a few hours to a few days during the current preview phase
6. You receive an email confirmation with the download link for your operating system

There is no waitlist in the traditional sense — it is rolling access, and most applicants in India are being approved within 24 hours as of March 2026.

Key Features in Public Preview

Gemini Agent

The core of Antigravity. You describe tasks in natural language and the agent:

• Reads relevant files in your project
• Plans the implementation approach
• Makes the changes across multiple files
• Runs tests if they exist
• Reports results and asks for confirmation

Unlike Cursor's Composer (which is also excellent), Antigravity's agent has deeper integration with Google's tooling — particularly Google Cloud services, Firebase, and Android development.

Codebase Indexing

Antigravity indexes your entire codebase on first open. This lets the agent understand project architecture, dependencies, and patterns before you give it any instructions. Ask "why is the login flow failing?" and it searches the relevant code rather than asking you to specify files.

Multi-Model Selection

You can switch between:

• Gemini 3.1 Pro (default — excellent for most tasks)
• Gemini 3.1 Flash (faster, good for simple tasks)
• Gemini 3.1 Pro Ultra (Jio Pro users and paid tier)

Terminal Integration

Antigravity integrates with your terminal. The agent can run build commands, tests, and scripts, interpret the output, and iterate automatically.

Google Cloud Integration

Native integration with Google Cloud services — deploy to Cloud Run, interact with Firestore, manage Cloud Functions — all from within the editor with AI assistance.

Antigravity vs Cursor — 2026 Comparison

| Aspect | Google Antigravity | Cursor | |--------|-------------------|--------| | Current status | Public preview (free) | Generally available | | Base model | Gemini 3.1 Pro | Claude Sonnet 4.6 / GPT-5.3 | | Agent capability | Core feature | Composer (excellent) | | Ecosystem | Google Cloud native | Agnostic | | VS Code compatibility | Limited (own interface) | Full VS Code extension compatibility | | Maturity | New (Nov 2025) | Mature (2023+) | | India pricing | Free preview | $20/month or 1yr free student | | Best for | Google ecosystem, Android | General web/backend dev |

For most Indian developers working with web backends, Next.js, or Python APIs, Cursor currently has better multi-file editing maturity. But for Android development, Google Cloud projects, or Firebase apps, Antigravity's native integrations make it a strong choice.

💰 Free Deal: The public preview is free with no commitment. There is no credit card required. Use it alongside Cursor or Windsurf rather than replacing your current setup — evaluate it on a real project to form your own opinion.

Practical Use Cases

Android app development: Antigravity has the best AI assistance for Android development among any current tool — it understands Jetpack Compose, Gradle, and Android APIs natively.

Firebase projects: Building a real-time app with Firestore? Antigravity can generate secure Firestore rules, Cloud Functions, and client SDK code with proper error handling.

Python/FastAPI backends that deploy to Cloud Run: The Google Cloud integration means you can describe your API, have it generated, and deploy it to Cloud Run in one session.

Learning programming: Because Antigravity explains what it is doing and why, it is a useful learning tool. Watch the agent implement a feature and understand the reasoning.

What to Watch For

Antigravity is still in preview, which means:

• Some features are still being developed
• Occasional bugs and interface changes
• Feedback from early users is shaping the final product
• The free period will likely end when it exits preview (pricing not announced as of March 2026)

If you are evaluating it, use it now while it is completely free.
